Nix does something like: ```cpp NixStringContext context; const auto str = state.forceString(*args[1], context, pos, "while evaluating the second argument passed to builtins.split"); ``` And then do nothing with that context, therefore, we follow them and make `split` aware of the context but still do nothing with it.

2023-12-14 r/7218 fix(tvix/eval): remove incorrect imports when coercingsterni1-14/+79
The default behavior of string coercion in C++ Nix is to weakly coerce and import to store if necessary. There is a flag to make it strongly coerce (coerceMore) and a flag that controls whether path values have the corresponding file/directory imported into the store before returning the (store) path as a string (copyToStore). We need to implement our equivalent to the copyToStore (import_paths) flag for the benefit of weak coercions that don't import into the store (dirOf, baseNameOf, readFile, ...) and strong coercions that don't import into the store (toString). This makes coerce_to_string as well as CoercionKind weirder and more versatile, but prevents us from reimplementing parts of the coercion logic constantly as can be seen in the case of baseNameOf. Note that it is not possible to test this properly in //tvix/eval tests due to the lack of an appropriate EvalIO implementation being available. Tests should be added to //tvix/glue down the line.

2023-12-12 r/7176 feat(tvix/eval): nonrecursive coerce_to_string()Adam Joseph1-6/+21
After this commit, the only non-builtins uses of generators are: - coerce_to_string() uses generators::request_enter_lambda() - Thunk::force() uses generators::request_enter_lambda() That's it! Once those two are taken care of, GenCo can become an implementation detail of `builtins::BuiltinGen`. No more crazy nonlocal flow control within the interpreter: if you've got a GenCo floating around in your code it's because you're writing a builtin, which isn't part of the core interpreter. The interpreter won't need GenCos to talk to itself anymore. Technically generators::request_path_import() is also used by coerce_to_string(), but that's just because the io_handle happens to be part of the VM. There's no recursion-depth issue there, so the call doesn't need to go through the generator mechanism (request_path_import() doesn't call back to the interpreter!)

2023-12-12 r/7166 fix(tvix/eval): never use partial_cmp() (partial fix b/338)Adam Joseph1-1/+1
This is part of a fix for b/338. We should never use PartialOrd::partial_cmp(). All Nix types except floats are obviously totally-ordered. In addition, it turns out that because Nix treats division by zero rather than producing a NaN, and because it does not support "negative zero", even floats are in fact totally ordered in Nix. Therefore, every call to PartialOrd::partial_cmp() in tvix is an error. We have to *implement* this function, but we should never call it on built-in types. Moreover, nix_cmp_ordering() currently returns an Option<Ordering>. I'm not sure what was going on there, since it's impossible for it to return None. This commit fixes it to return simply Ordering rather than Option<Ordering>.

2023-11-03 r/6930 refactor(tvix/eval): more efficiently intersect attributesVincent Ambo1-9/+70
builtins.intersectAttrs is used a _lot_ in nixpkgs eval, for whatever reason. We previously had a very inefficient implementation that would allocate for each comparison. It stuck out like a sore thumb in perf analysis. This moves to a custom algorithm with two iterators, one for the left and one for the right side, advancing them along the (borrowed) map keys until a match is found and allocation is required. I've not made any effort to reduce the verbosity of this code, I don't think it's worth it. On my machine this reduces the mean runtime of evaluating `nixpkgs.emacs.outPath` by ~8%.

2023-07-22 r/6439 feat(tvix/store/proto): use Bytes instead of Vec<u8>Florian Klink1-2/+4
Makes use of https://github.com/tokio-rs/prost/pull/341, which makes our bytes field cheaper to clone. It's a bit annoying to configure due to https://github.com/hyperium/tonic/issues/908, but the workaround does get the job done.

2023-07-21 r/6436 refactor(tvix/store): use bytes for node names and symlink targetsFlorian Klink1-1/+2
Some paths might use names that are not valid UTF-8. We should be able to represent them. We don't actually need to touch the PathInfo structures, as they need to represent StorePaths, which come with their own harder restrictions, which can't encode non-UTF8 data. While this doesn't change any of the wire format of the gRPC messages, it does however change the interface of tvix_eval::EvalIO - its read_dir() method does now return a list of Vec<u8>, rather than SmolStr. Maybe this should be OsString instead?

2023-06-20 r/6336 fix(tvix/eval): only finalise formal arguments if defaultingsterni1-1/+2
When dealing with a formal argument in a function argument pattern that has a default expression, there are two different things that can happen at runtime: Either we select its value from the passed attribute successfully or we need to use the default expression. Both of these may be thunks and both of these may need finalisers. However, in the former case this is taken care of elsewhere, the value will always be finalised already if necessary. In the latter case we may need to finalise the thunk resulting from the default expression. However, the thunk corresponding to the expression may never end up in the local's stack slot. Since finalisation goes by stack slot (and not constants), we need to prevent a case where we don't fall back to the default expression, but finalise anyways. Previously, we worked around this by making `OpFinalise` ignore non-thunks. Since finalisation of already evaluated thunks still crashed, the faulty compilation of function pattern arguments could still cause a crash. As a new approach, we reinstate the old behavior of `OpFinalise` to crash whenever encountering something that is either not a thunk or doesn't need finalisation. This can also help catching (similar) miscompilations in the future. To then prevent the crash, we need to track whether we have fallen back or not at runtime. This is done using an additional phantom on the stack that holds a new `FinaliseRequest` value. When it comes to finalisation we check this value and conditionally execute `OpFinalise` based on its value. Resolves b/261 and b/265 (partially).
